Signs That It’s Time to Harvest Potatoes
Knowing when to harvest potatoes is crucial to ensure that you harvest them at the peak of maturity, resulting in better flavor, texture, and overall quality. Harvesting too early can mean smaller tubers, while waiting too long may lead to larger tubers but a decline in taste and storage potential. Here are some signs that indicate it’s time to harvest your potatoes:
1. Flowering and Foliage: Pay attention to the flowering stage of your potato plants. When the plants start to flower, it is an indication that tuber growth has begun. While not a definitive sign on its own, flowering can be an initial cue that harvest time is nearing.
2. Foliage Senescence: As the potato plants near maturity, the foliage will start to turn yellow and begin to die back. Once about 50-60% of the foliage has withered or turned brown, it’s a sign that the tubers have likely reached maturity and are ready for harvest.
3. Skin Texture: Gently brush away some soil around the base of the plants and inspect the skin of a few potato tubers. Mature potatoes will have a relatively thick and well-set skin compared to younger tubers. The skin should be firm, smooth, and resistant to scraping or flaking off easily.
4. Tuber Size: Check the size of a few potato tubers to determine if they have reached the desired size for harvesting. The size varies depending on the potato variety, but most varieties are ready for harvest when the tubers have reached their mature size. Avoid leaving potatoes in the ground for too long, as they may eventually become oversized and lose flavor.
5. Tuber Set and Growth: Evaluate the overall development of the potato tubers. Mature potatoes have fully developed sets and should exhibit good growth and plumpness. Look for well-formed, fully developed tubers that have filled out the space around them.
6. Taste and Texture: For some gardeners, the final test is to sample a few potatoes to judge their taste and texture. Harvest a few potatoes and cook them to assess their flavor, texture, and suitability for your culinary needs. This taste test can provide valuable insights into the readiness of the remaining crop.
7. Storage Considerations: Consider your storage plans for the harvested potatoes. If you plan to use them immediately, you can harvest them when they are smaller and more tender.

2. Observe foliage senescence: Pay attention to the foliage of the potato plants. As the tubers near maturity, the foliage will start to turn yellow and begin to dry out. Once the foliage has withered and the majority has turned brown, it’s a good indication that the potatoes have reached maturity.
3. Perform the “gentle squeeze” test: Carefully dig up one or two test hills to assess the maturity of the tubers. Gently squeeze or press the tubers between your thumb and forefinger. Mature potatoes will have a firm texture, while immature ones will feel soft or spongy. If the tubers are still too firm and resistant to pressure, allow more time for them to mature before harvesting.
4. Assess the skin set: Another method is to examine the skin of a few potatoes. Mature potatoes will have a relatively thick and well-set skin that doesn’t easily scrape or flake off. If the skin is easily removed or the potatoes have a thin, delicate skin, they may not be fully mature and should be left in the ground for longer.
5. Monitor tuber size: Compare the size of the harvested potatoes to the estimated mature size of your variety. While size can vary, most potatoes are ready for harvesting when they have reached their mature size. Avoid leaving them in the ground for too long, as they may become oversized and lose their desired texture and flavor.
6. Perform a taste test: For the final assessment, cook and sample a few potatoes to determine if they have reached the desired taste and texture. Boil, roast, or prepare them as you typically would in your preferred culinary recipes. Harvest the remaining potatoes if the sample potatoes meet your taste expectations.
7. Time it with the weather: If possible, schedule your potato harvest during a period of dry weather. Avoid harvesting potatoes when the ground is excessively wet, as this can lead to mud-caked potatoes that are more challenging to clean and properly store.
8. Store properly: After harvest, handle potatoes gently to prevent bruising and damage. Clean them gently, removing excess soil, but avoid washing them unless necessary. Allow the harvested potatoes to dry and cure in a well-ventilated area before storing them in a cool, dark, and dry place for long-term storage.
By following these tips, you can ensure that you harvest your potatoes when they are at their prime, resulting in the best taste and quality. Adjust your harvesting time based on these indicators, your preference for texture, and your storage plans for the potatoes.
